Dental floss based on polyamide includes three sections passing one into another. The first section is made of fibers bonded to form a solid thread, has a length of not more than 70 mm in a taut state, the second section is made with the formation of a filamentous thread and has a length of not more than 200 mm in a taut state, the third section is made of fibers bonded to form a flat thread, and has a length of not more than 220 mm in a taut state. The technical problem is to expand the functionality while providing a technical result - increasing the efficiency and rapid cleaning of the dentition in people with any combination of interdental spaces (wide, narrow, standard) and / or interdental orthodontic or orthopedic constructions.

Description

The utility model relates to devices for oral hygiene, cleaning the interdental spaces of natural teeth and teeth with bracket systems. In the art, one of the technical challenges is the need to effectively and quickly clean the dentition of users with bracket systems while effectively cleaning the interdental spaces of the natural teeth of these users.

The following means of the same purpose as the proposed utility model are known from the prior art.

From the description to patent RU 107046 (published on August 10, 2011), a dental floss is known, including two alternating sections: a flat section of the thread, having a length of 4 cm, and a section of a filamentous thread, represented by a spongy form, having a length of 1.5 cm.

The use of well-known dental floss has some negative features. In particular, threading the floss into the interdental space is difficult, since the floss is not rigid, therefore, getting the floss into the interdental space provides for the development of skills developed over time, which makes the process of cleaning the interdental spaces of teeth with bracket systems longer.

From patent RU 171540 (published on 06/06/2017) a dental floss is known that has two alternating sections of different shapes: one section is straight with a flat thread shape, the second section is made in the form of a sinusoid with slightly pointed vertices. When using this dental floss, the reasons similar to those mentioned above when mentioning the analogue of RU 107046 appear, that is, the non-rigid tip of any section of the floss does not provide quick access to the interdental space. In addition, for the manufacture of a section with denticles, equipment is required that provides for the manufacture of means that provide a zigzag shape of the second section.

Oral-B Super Floss dental floss (manufacturer Procter & Gamble/Procter & Gamble) is known from information widely available on the Internet. For example, on the web pages https://www.medkv.ru/zubnaya-nit-oral-b-super-floss-50-nitej.html, https://dent-mart.ru/Interdental-Oral- B-Super-Floss-50-pcs-by-60-cm-p48222528 Oral-B Super Floss has been reported to be used for cleaning bridges, braces, implants and wide gaps between teeth. Oral-B Super Floss dental floss is presented in pieces of dental floss, packed in a carton box of 50 pieces. Each section of Oral-B Super Floss includes three sections that flow into one another, namely: the first section is a hard fiber for insertion under and between orthodontic and orthopedic structures, the second section is a spongy fiber for removing plaque and food debris between wide interdental spaces, the third section is attached to a dental floss known from the prior art, designed to clean the standard interdental spaces of natural teeth.

The technical solution embedded in the product - dental floss Oral-B Super Floss, was chosen as the closest analogue to the proposed utility model.

The known dental floss Oral-B Super Floss does not have sufficient universal property, since each of the sections of the thread is not designed to penetrate into narrow areas of the interdental space with the ability to effectively clean the narrow interdental spaces in the user's mouth, for example, when teeth are crowded. Thus, the first part of the floss is a rigid section, represented by a hard fiber for the penetration of dental floss under and between orthodontic and orthopedic structures; the second section is represented by a spongy fiber and is intended for cleaning wide interdental spaces, the third section is represented by a fiber of a round or oval section for areas of an even row of teeth that do not have the features described above. The disadvantage of this dental floss is the lack of effectiveness when used by users who have orthodontic and orthopedic structures in the oral cavity, while they have narrow sections of the interdental space in their oral cavity, for cleaning which requires a flat form of dental floss, which easily penetrates into hard-to-reach narrow areas of the interdental space. space, along the gum line and well cleans closely spaced teeth, for example, with crowded teeth.

The disadvantage of the closest analogue is also that the presented different shape of the sections of the dental floss does not take into account the natural individual features of the structure of the human oral cavity, which can combine both wide and narrow interdental spaces, while the “spongy” shape of the site is suitable for cleaning wide interdental spaces. flossing does not effectively clean the narrow interdental spaces that flat-shaped dental floss is designed to clean. Thus, while cleaning wide areas of interdental space well, this floss is less effective at cleaning narrow interdental spaces that are located in the same oral cavity of users with orthodontic and orthopedic constructions.

The technical problem solved by the utility model is to expand the functionality while providing a technical result - increasing the efficiency and quick cleaning of the dentition in people with any combination of interdental spaces (wide, narrow, standard) and / or interdental orthodontic or orthopedic constructions.

The solution of the stated technical problem with the achievement of the claimed result is ensured by the fact that the polyamide dental floss consists of a thread, which is a fiber of circular cross section, with three sections passing one into another, the first section being made of fibers bonded to form a solid thread, the second section is made with the formation of a filamentous thread, the third section is made of fibers bonded to form a flat thread.

The first section in the form of a solid thread, due to its hardness, allows the threads to easily pass under orthodontic or orthopedic constructions or for insertion through the gingival part of the interdental space. The second section in the form of a filamentous thread is intended for cleaning orthodontic structures, standard and wide interdental spaces of natural teeth. The third section is designed for cleaning narrow interdental spaces of natural teeth, including those with crowded teeth.

Based on the foregoing, it follows that the proposed dental floss, consisting of three successive sections that have their own purpose, expands the functionality of the dental floss. Thus, a user having a combination of, for example, different interdental spaces, or different interdental spaces and orthodontic and prosthetic constructions, or other combinations thereof, does not need to use separate threads, in which case the three sections of one thread perform the corresponding functions.

The cross section of the second section of the dental floss segment is used both for cleaning the lateral surface of the tooth and for simultaneously cleaning the lateral surface of neighboring teeth, the distance between which has wide gaps, and the flat shape of the third section of the dental floss segment is used for cleaning the lateral surface of the tooth, and for simultaneous cleansing the lateral surface of neighboring teeth, the distance between which has narrow gaps, including when the teeth are crowded.

The most effective cleaning of the interdental space from plaque and food debris is achieved by the user due to the possibility of using both the second and third sections of the pieces of dental floss, depending on the user's need to clean both narrow and wide interdental spaces simultaneously present in his oral cavity. The cleaning of the treated surface of the teeth is carried out by the user by reciprocating movement of the second or third section of the dental floss along the treated surface back and forth and up and down.

The piece of dental floss used by the user to clean the dental gaps can have the following lengths: the first section has a length of no more than 70 mm in a taut state, the second section has a length of no more than 200 mm in a taut state, the third section has a length of no more than 220 mm in a taut state . This length of sections of the segment of the dental floss due to the following features when using.

The first solid section of dental floss, which is sufficiently rigid and intended only to facilitate the passage of dental floss through orthodontic and orthopedic structures, has a length of no more than 70 mm in a taut state. Since the first section is not intended for cleaning dental spaces, this section length is sufficient for the user to comfortably hold it with the fingers of both hands when inserted under and between orthodontic and orthopedic structures or between narrow interdental spaces.

The length of the second and third sections of the dental floss is determined by the number of dental spaces in humans. So, a person has 32 teeth in his mouth. In the upper and lower jaws of a person, there are 16 teeth each and, as a result, 15 interdental spaces, in total there are 30 interdental spaces in the human oral cavity. For effective cleaning of one narrow interdental space, at least 10 mm of dental floss is used, and for a wide interdental space, at least 13 mm, so that the dental floss and the tooth surface to be cleaned have tight contact and qualitatively remove plaque and food debris. At the same time, all of the user's interdental spaces cannot be narrow or wide, so even if at least in the user's mouth half of all interdental spaces are wide and half are narrow, the length of the second floss for cleaning wide of interdental spaces and a length of no more than 220 mm of dental floss for cleaning narrow interdental spaces is sufficient to effectively clean each interdental space.

For the manufacture of dental floss, a thread consisting of polyamide fibers of round cross section with a diameter of 17 to 20 microns is used. Mentioned first and third sections of the dental floss are formed by passing a filamentous thread through two heated to a certain temperature or closed due to compression by the force of the mold, the second section remains in a loose form and is not subjected to the specified processing. At the output of the production line, the dental floss is cut into equal segments, each segment of the dental floss has the shape of three sections passing one into the other. The first section has the same cross-sectional diameter along its entire length, the second section also has the same cross-sectional diameter along its entire length. The third section has the shape of a flat rectangle of the same height, width and depth along its entire length.

Pieces of dental floss are placed in an individual plastic bag, which is packed inside a cardboard or plastic box. The number of pieces placed in an individual plastic bag, which is packed inside a cardboard or plastic box, can be 50, 70, 100 or more pieces.

Figure 1 (Figure 1) shows a general view of the dental floss under each section of its cross section, where:

1 - the first section, made with the formation of a solid thread;

2 - the second section, made with the formation of a filamentous thread;

3 - the third section, made of fibers bonded to form a flat thread.

Declared dental floss is used as follows.

A piece of dental floss is pulled out from an individual plastic bag packed in a cardboard or plastic box. The user wraps this section around his fingers, and, depending on which section he intends to use to clean the interdental space, the user holds on to certain areas. When flossing is inserted into the oral cavity under and between the orthodontic and prosthetic structures, the user holds on to a first, hard section of the floss that is sufficiently stiff to only facilitate the passage of the floss through the orthodontic and prosthetic structures. If it is necessary to clean the interdental space with wide interdental spaces or bracket systems, as well as the interdental space with narrow interdental spaces, including crowding of teeth, the user uses the second or third sections with a back and forth and up and down movement along the treated surface floss, with the user's left hand holding the second section, the right hand holding the end of the third section.
